SciDB-Py: Python Interface to SciDB
Version Information
The major and minor version numbers of SciDB-Py track the major and
minor version of SciDB they are compatible with. For example SciDB-Py
16.9.1, 16.9.2 or 16.9.10 are all compatible with SciDB
16.9.x.
During SciDB 16.9, Shim (HTTP service for SciDB) transitioned from
query authentication to session authentication. SciDB-Py has been
updated to be compatible with the new Shim. Below is the compatibility
matrix between SciDB-Py and Shim:
| SciDB-Py | Shim |
|---|---|
16.9.1 |
query authentication (old Shim) |
16.9.2 |
query authentication (old Shim) |
16.9.10 |
session authentication (new Shim) |
From 16.9.10 onwards only Shim with session authentication is
supported.
Since SciDB-Py Release 16.9.1 (released in September 2017) the library has been rewritten entirely from scratch. 16.9.1 and newer versions are not compatible with the previous versions of the library. The documentation for the previous versions is available at SciDB-Py documentation (legacy). GitHub pull requests are still accepted for the previous versions, but the code is not actively maintained.
Requirements
SciDB 19.11 or newer with Shim
Python 3.5.x, 3.6.x, 3.7.x, 3.8.x, 3.9.x, or 3.10.x
Required Python packages:
backports.weakref enum34 numpy pandas (see version requirements in setup.py) pyarrow (see version requirements in setup.py) requests six
CentOS 6 and Red Hat Enterprise Linux 6
CentOS 6 and Red Hat Enterprise Linux 6 come with Python
2.6. SciDB-Py requires Python 2.7 or newer (see above). The
default Python cannot be upgraded on these operating systems. Instead
a different Python version can be installed in parallel using
Software Collections. For
example, here are
the instructions to install Python 2.7 using Software Collections.
Installation
